- invention relates to one-horse, twowheel and row manure spreaders, andhas for its object anovel construction and arrangement of theunloadingmechanism, being a division -of1n1y. Patent No..1,642,798, datedSeptember 20, 1927. j

" I believe itto be novel toprovidea chain drag, mountedjon and operatedby a shaft passingthrough the .bodyf of the manure ,spreaderandbroughtinto and out of, opera- 1 tive position by means of a hand levermountzed on the rear of the two-wheeled cart,,so that thelifting powerwill. be applied by a pull directly through a link "or. flexibleconnection from the hand lever to the unloading device I from the rearof the cart.

' Other'details of construction and arran e ment of parts willhereinafter be particularly describedand claimed. I l

Referring to the drawings, in which like parts are similarly designated-Figure 1 is a side view of so much of a I manure "spreader as will benecessary for an understanding of my invention.

' Fig. 2 is a plan view thereof.

Fig. 3 is'a vertical longitudinal section. My manure spreader isin theform of a cart, having a body 1, shafts 2, an axle 3 and 1 Wheels 4. Onthe axle is mounted a sprocket & 33

wheel driven by one of the wheels 4. This sprocket wheel is providedwith a sprocket chain 11 that passes over a sprocket wheel 17 loose on ashaft 18. A chain tightener comprising an arm 19 pivoted on a bolt 20carrying a roller 21, engages the chain and takes 'up theslack,'maintaining the chain taut.

The arm 19 is loaded by a spring 22, and the roller engages the chainbetween the sprocket wheels 12 and 17. p

The loose sprocket wheel 17 is connected to a shaft 18 by a clutch whosemovable support member-23 is urged into driving connection by a spring24. This member is operated by a shifting arm 25 having a hole 26 inwhich a hook 27 may be placed to hold the clutch disconnected totemporarily prevent the unloading mechanism from operating While goingfrom barnyard to field. The unloading device has several sprocket wheels28 secured thereto.

lifting arm.

Pivoted at one end on shaft 18 is a frame composed of longitudinalmembers 29 and adjustable, transverse member. 30 and crossed braces31.At the opposite end of the frame is a shaft 32 carrying sprocket wheels33,

similar to those 28 and similarly spaced.

Over each pair of sprocket wheels 28, 33,

is .a drag chain 34 provided with any kind of suitable drags 35. I

A sector 36 having teeth at its rear portion and a plain are 37 at itsfront portion is mounted on the body, as, shown. The sector is. securedto an iron 50 having an eyesupported by shaft 18 and a. hook portion 51en- I gaging over the rear board 15 of the body. A liftingarm 38provided with the custom- ;ary hand-operated latch 39 is pivoted to rideover said sector. The arm 38 isconnected to the frame by a link 40,preferably at the crossing of the braces 31. A spring 41 is connectedbetween the sector or'other stationary part and the frame, to partiallyrelieve the load of the unloading mechanism on the 42 is a rollermounted in brackets 43 for supporting the upper stretches of the dragchains 34, and for tightening said chains.

The operation of my manure spreader is as followszl j i v Assume theunloading device to be lifted and latched. the body 1 .to be loaded, andthe thrown into engagement and the drag chains rotated, the lowerstretches acting on the surface of the load and gradually delivering theload over the rear edge of the bottom 5.

The latch 39 riding on the untoothed portion 37 ofthe sector 36 allowsthe frame and chains to lower in accordance with the discharge of theload, until it reaches a posi tion. parallel or nearly parallel with thefioor'5. I I

3. In a manure spreader, a body, a rotatable shaft therein, sprocketwheels on said shaft, a frame pivoting on the shaft at one end, a; shafton the opposite end of said frame, sprocket wheels on the latter shaftand drag chains between the sprocket wheels on the two shafts; incombination with a roller mounted on said frame between its ends andarranged to support the upper stretches of the drag chain, a hand leverand a tension memberconnectmg the lever and frame to manually move theframe;

4. Inaimanure spreader, a body, a gravityfeed unloading mechanismpivoted at one end ofsaid body, in combination with a manuallyoperatedlever and latch, a sector therefor,

means connected atone end between the ends of the lever and at the otherend to said mechanism and a spring sustaining part of the load of saidmechanism."

5. In a manure spreader, a body, a gravityfeed unloading mechanism, adrivingshaft- T therefor on which the mechanism pivots, an

iron having one end mounted. on said shaft and means on the other end tosecure it to one end of said body, a sector supported on said iron, apivoted hand lever 00-operating with said sector, and a connectingmemberattached at one end to, said lever and at the operated lever and latch,a sector therefor, Y

and an element connected atone end to the unloading mechanism and at itsother end to said lever, said lever acting through said element to raisethe mechanism andholdthe mechanism elevated by said latch. c

8. In a two-wheeled, one horse, manure spreader, including a body, agravity-feed unloading mechanism pivoted'in one end ofthe body andmechanism operated from a wheel to operate the unloading mechanism; ahand lever pivoted to the rear of the pivotalaxis the lever in differentangular'p'o'sitions, and

a single element .connected atone end to'the lever and atthe other endto the unloading mechanism, whereby said lever may raise the unloadingmechanism by manual operation of the lever. 1 '7 V 9.
